GBT13A-424

Completing a GBT Timing Campaign of 11 Pulsars Discovered in the PALFA Survey

Abstract

The PALFA survey is a major survey of the Galactic Plane using Arecibo and has discovered 99 new pulsars. Constraining the nature of newly discovered pulsars demands follow-up timing observations for a full year in order to determine spin and binary parameters, hence fundamental properties such as ages, magnetic fields, and spin-down luminosities. We have been using a variety of telescopes to time different pulsars where appropriate: the Lovell telescope for the brightest pulsars and Arecibo for the faintest pulsars. We were also awarded up to 42 hours of GBT time during the 12B semester to time 10 pulsars and one RRAT to relieve pressure on Arecibo, which suffers from stringent hour angle constraints. To complete this project and make full use of already-awarded GBT time, we require an additional 18 hours of GBT time during the 13A semester. This will allow us to measure precisely the position and spin-down of the pulsars, important input for population studies and for maximizing the scientific return of the PALFA survey.
